KUALA LUMPUR – Perak Man, the 11,000-year-old skeletal remains found 30 years ago in the Lenggong Valley of Perak finally has a face.
A team of researchers from Universiti Sains Malaysia (USM) and 3D graphics expert from Brazil, Cicero Moraes had used the 3D virtual reconstruction method to reconstruct the Perak Man’s facial features.
Oral and Maxillofacial Radiology lecturer at USM School of Dental Sciences, Dr Johari Yap, who is also one of the researchers said that the project was mooted two years ago by Senior Consultant Neurosurgeon Prof Datuk Dr Jafri Malin Abdullah.
Sharing the story with Bernama, Johari said that Dr Jafri, who had conducted many studies related to neuroscience and cognitive, had invited him to reconstruct the hypothetical face of the Perak Man.
Johari, who has the expertise in craniofacial imaging and 3D reconstruction and analysis of faces and skulls, said that a copy of the original skull was made using computed tomography (CT) and 3D printing.
Johari said, before reconstructing the face, Moraes needed information such as gender, age and lineage to produce facial tissue based on the average tissue thickness measured during previous studies.
“Once the face is formed, we will discuss about eye colour, skin colour and hair based on forensic anthropology.
“Because Perak Man is referred to as Australo-Melanesian and the descendent of Negrito ethnic group, the features of Negrito people greatly influenced the final image,” he said.
Perak Man, the most complete skeleton found in Southeast Asia was uncovered at Gua Gunung Runtuh by a team or archaeologists led by Prof Datuk Dr Zuraina Majid in 1990.
The excavation revealed a 10,000 – 11,000-year-old primary burial site of an adult man buried in the foetal position.
The funerary artefacts indicate that Perak Man was highly respected, as he was buried at the centre of the highest cave in Lenggong and he was the only person buried there.
Apart from Johari, Dr Jafri and Moraes, four other researchers are USM Centre for Global Archaeological Research Director Prof Datuk Dr Mokhtar Saidin, Dr Helmi Hadi from USM School of Health Sciences, Prof Dr Zainul Ahmad Rajion from USM School of Dental Sciences and USM School of the Arts lecturer Norshahidan Mohamad.
Johari said the estimated volume of Perak Man’s intracranial volume (ICV) was 1,204.91mL, which was smaller than modern human’s cranial capacity of between 1,312 mL and 1,479 mL and this may indicate a physical handicap.
“Despite being born with a physical handicap, Perak Man survived and lived a nomadic hunting and gathering lifestyle, probably due to considerable care given to him. He may have overcame his physical handicap by developing proficient hunting skills or perhaps, he rarely hunted and took on other tasks.
“Based on his presumed status, Perak Man was likely a respected person in the group and perhaps, a shaman and the most knowledgeable person in the group regarding survival, hunting, gathering and other aspects of Paleolithic daily life.
“Perak Man likely lived as a hunter, similar to the lifestyle of Negrito ethnic group, which could be the descendant of Perak Man,” the researchers wrote in an editorial published in the Malaysian Journal of Medical Sciences. -BERNAMA
